Axial adiabatic fixed bed reactor

Abstract

The invention relates to the technical field of reactor equipment, and discloses an axial heat insulation type fixed bed reactor which comprises a fixed tank and an elastic rope, fixed rings are uniformly and fixedly mounted in the fixed tank, one end of the elastic rope is fixedly connected with the interior of each fixed ring, and the other end of the elastic rope is fixedly connected with the interior of each fixed ring. The other end of the elastic rope penetrates through the fixing tank and the fixing ring and then is fixedly connected with a tensioning arc-shaped plate, and catalyst blocks are evenly and movably installed on the elastic rope and located in the fixing tank. Through the arrangement of the elastic rope and the catalyst blocks, the inner cavity of the fixed tank is layered, heat is released after materials above the catalyst blocks react, the pressure above the catalyst blocks is increased, then the catalyst blocks are pressed to descend, the catalyst blocks are separated, and the materials are released to the next layer to react, so that the situation that the pressure is too large and the heat is too high is effectively avoided; therefore, the material can be discharged after being fully reacted, and the quality of the product is improved.

Description

technical field [0001] The invention relates to the technical field of reactor equipment, in particular to an axial adiabatic fixed-bed reactor. Background technique [0002] Fixed bed reactor refers to the filling of granular solid catalyst or solid reactant in the reactor to form a stacked bed of a certain height, while the gas or liquid material flows through the static fixed bed through the particle gap to realize the heterogeneous reaction process The characteristic of this reactor is that the solid particles filled in the equipment are fixed, which is different from the moving bed and fluidized bed in which the solid material moves in the equipment, also known as the packed bed reactor. The fixed bed reactor currently used There are some deficiencies, as follows: [0003] The currently used fixed-bed reactors usually use granular or briquette-like catalytic particles to form the bed, but the granular catalytic particles are discharged irregularly in the reactor.

AI Technical Summary

Problems solved by technology

[0003] The currently used fixed-bed reactors usually use granular or briquette-like catalytic particles to form the bed, but the granular catalytic particles are discharged irregularly in the reactor. Discharge, easy to cause local blockage, on the one hand, it is easy to block the flow of materials, affecting the discharge of materials after reaction; Catalyst seat flows irregularly, and some materials passing through the gap may be discharged before they have time to react, which will affect the purity of the reacted materials
